Description

Enables an address or prefix to be allocated on demand when a dual-stack subscriber session is established. Starting in Junos OS Release 18.1R1, when reauthentication is configured, enables per-family address allocation as each family’s DHCP session is established. In earlier released, applies only to the second family of the dual stack.

Note:

You must configure on-demand-address-allocation if you also configure reauthentication for dual-stack, single-session DHCP subscribers. This is true whether you enable reauthentication with the reauthenticate statement or the Reauthenticate-On-Renew VSA (26-206).

Required Privilege Level

system—To view this statement in the configuration.

system-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 17.3R1.
